ABSTRACT:
An apparatus for opening radiographic cassettes comprises a housing which may be closed in a light-tight fashion and containing a platform onto which the radiographic cassette is positioned. Also, in the housing is an elongated upwardly inclined cam surface which engages a lip portion projecting from the cover of the cassette. When pushing the cassette further into the housing the cover becomes gradually lifted by the cam action. At a given position the cover is lifted sufficiently open to permit the introduction and removal of unexposed and exposed film into and out of the cassette. A release mechanism, upon actuation, enables the cassette cover to drop thereby closing and relocking the cassette.
The apparatus is suitably incorporated in a daylight system for loading radiographic cassettes with unexposed radiographic films.
